to evaluate the effect of different levels of nitrogen fertilizer and municipal compost on the essential yeild of savory pot experiment in 2009 was carried out in the darab region. different doses of compost was in four levels, including: zero c0:, 10c1:, 20c2: and 30c3: tons per hectare and nitrogen fertilizer include: zero n0:, 30n1:, 60 n2: and 90n3: kg of pure nitrogen from urea per hectare...

Building a 2,000-square-foot house leaves about a ton of gypsum wallboard waste from end cuts, window and door cutouts, and broken boards. In the United States, three million tons of gypsum wallboard waste is dumped in landfills each year. In addition to depleting space, microbial action can decompose gypsum to malodorous hydrogen sulfide gas, which at high enough exposures can cause irritation...

Abstract Accumulation of high level nitrate (NO 3 ? ) in leaves is a serious issue for vegetable crops like lettuce ( Lactuca sativa L.). Therefore, this study aimed to limit NO by adjusting the balance between fertilization and irrigation program lettuce. In strip plot design with three replicates, plants were grown under four fertilizer treatments regimes. Three organic fertilizers (biochar, ...

     As an herbaceous, perennial, and evergreen plant, Vetiver Grass (Chrysopogon zizanioides L.) can be used for the improvement and development of arid and semi-arid rangelands. To assess the interaction effect of organic and biological fertilizers on the growth and physiological traits of Vetiver grass, the dry weight of shoots and roots, essential oils, chlorophyll, carotenoids, and proline...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...

Organic fertilizers are generally thought to be an effective way to sustain soil fertility and plant growth. To promote the productivity of chrysanthemum, five sources of liquid organic fertilizers (L1–L5), as well as a chemical fertilizer, were applied at an early stage of the growth cycle to investigate their effects on plant growth. In the short-term pot experiment, the liquid organic fertil...

This study was conducted in 2018, under open field conditions Ad?yaman Province of Turkey to determine the effects farm manure, vermicompost and plant growth regulators on yield some fruit quality parameter watermelon. Matured three different (Crop-Set, Endoroots ISR-2000) were used compare with control (not fertilizers applied) application. Vermicompost, Endoroots, ISR-2000 Crop-Set applied pl...
